Various other ways have been employed thicknessk throughout itsV entire extent. AThe for providing a smooth edge at the top of the` collar 8 is bent intermediate its side edges vas f5? container after it is open,`and a smooth edge at indicated at 15, so that the upper section 8a isv liv.

offset slightly from the lower section 8b. This collar 8 is inserted in the container during the manufacture thereof, and when there is a bead in the container it is preferably disposed so that the lower edge of the collar rests against said bead. The bead serves solely as a support for the collar, and does not in any way secure the collar to the container. The collar may be secured to the body ofthe container in any desired way. As shown in the drawings it is made of such size that when forced into the container it will frictionally grip the container wall and beheld in place. It may be secured by soldering or by bending the metal of the collar or the metal of the container. It is essential that it shall be firmly attached to the body of the container andbecome a part thereof, so that when the rip strip is removed this collar becomes the upper edge portion of the'body of the container and provides a smooth edge which will not in any way injure the hands of the user contacting therewith.

The collar 9 as shown in the drawing is clamped between the wall of the body and the well 16 formed by a depression in the collar. The collar is inserted between these walls, and when the double seam is formed the pressure exerted on the metal in the rolling of the double seam will cause these walls to firmly gripthe collar 9. The collarY 9, therefore, becomes rmly attached to the end which is separated from the body when the rip strip is torn away. It will be understood that Athis collar may be otherwise secured to the end which is'separated from the body.

When the rip strip is removed as shown in Figure 2 then the end which is separated from theA body may be lifted from the container. This makes an easy way of opening the container.

. The container can be reclosed by slipping the collar 9 down over the collar 8. These collars overlap before the rip strip is removed, and therefore serve as a support during the turning of the key to tear away the lrip strip. They also serve to retain the material in the container during the opening of the same.

While the container has been shown as provided with two inserted collars, it will be understood that other means may be provided on the separated end for cooperating with the collar on the Ybody for reclosure. On the other hand other means may be formed in the body wall for co- `operating.with the improved reclosure collar atattached to the body of the container below the lower score/line and projecting above said score line, said collar being formed by pressure applied to the metal whereby a smooth and unbroken edge is provided, and a collar attached to the end which is to be separated from the body by the removal of the rip strip, said last named collar being formed by pressure applied to the metal whereby a smooth and unbroken edge is provided, said collar attached to the body of thercontainer having the portion thereof above the lower score line inset away from the wall of the container, the thickness of the .collar attached to the end whereby said collar on the end may extend down over the collar on the body.
